Title: Improvements relating to electrical discharge tubes
IPC: H01J61/04
Filed: 1934-02-17
Abstract: 432,442. Discharge tubes. QUARZLAMPEN-GES., Hanau, Germany. Feb. 17, 1934, No. 5331. Convention date, Feb. 17, 1933. [Class 39 (i)] A gas- or vapour-filled discharge tube, such as a lamp, has one or more electrodes E which are heated to an electron - emitting temperature during operation and are each surrounded by a metal jacket M, which is electrically insulated therefrom, is not maintained at any fixed potential, and is supported on, but insulated from, an electrode leading-in wire by means of a glass bead G. The tube may be adapted to emit visible or invisible rays and the filling consists of an unsaturated vapour such as cadmium or mercury. Starting may be facilitated by a filling of argon and the provision on the tube wall of a strip which is connected to the electrodes and is interrupted in the neighbourhood of the cathode. The electrode E consists of two or more nested cups e.g. of nickel, between which electron-emitting, material is located or, alternatively, it may consist of plaited wire or ribbon having projections and hollows which house the electronemitting material. The jacket may be fitted with an apertured cover for the passage of the discharge, and is located, at least at one point, less than 5 mm. from the electrode so that it may be heated, to remove occluded gas, by a heavy discharge between the electrodes. In another form, the jacket has the shape of a frustum of a cone. The Specification as open to inspection under Sect. 91 states also that the jacket may be supported by members fused to the side tube wall or by a leading-in wire passing through the end of the tube. This subjectmatter does not appear in the Specification as accepted.

Abstract: 271,936. Brown & Barlow, Ltd., and Brown, C. March 1, 1926. Spray carburettors.-In a pilot jet system in which fuel is supplied through a conduit e when the throttle valve f is closed and through a conduit k when the valve f is slightly open, the fuel from the pilot nozzle c is supplied to the conduit k through a perforation i formed in a detachable and interchangeable, member g which can be removed without affecting the nozzle c or the conduit e. The member g is provided with an adjustable plug m formed with air inlet passages l, o, n, the passage n allowing a minimum inlet of air when the passages c are shut off by the seating of the coned end of the plug on the member g. The conduit e is formed in an interchangeable plug d. In operation, when the throttle valve f, which is shown slightly open in Fig. 2, is closed, air from the mixing-chamber enters through the conduit k and perforation i in addition to air admitted through the plug m, and mixes with the fuel supplied to the conduit e; when the throttle is slightly open, rich mixture is supplied through the conduit k. The throttle valve f may be provided with a perforation or perforations to allow the passage of a small quantity of air when the throttle is closed.

[Class 110 (i).] In an electric fan of the table, wall bracket or like type, the driving motor is surrounded by a hub rigidly secured to the motor shaft and adapted to carry fan vanes and forming a cover independent of and easily removable from the motor. A stream-lined hub 5 is fitted with a bush 8 mounted on the conical pin 10 of the motor 4. Slots 11 in the hub are arranged obliquely to its axis and may.be curved. They extend into openings 12 which allow the insertion into the slots of flexible vanes 6, such as described in Specification 368,204, and also serve for cooling the motor. The slots 11 for each vane may be displaced relative to one another in the peripheral direction. The motor is secured to an arm 3 which is pivoted on a base 2 so that it will remain in any desired position of angular adjustment. For this purpose the base of the arm has a cylindrical surface and is connected by a spring 15, arranged to counterbalance the weight of the motor, to a stud 18. Abutments 40 limit the angular movement. Pivotal movement in more than one plane may be obtained by the provision of a ball-joint. One lead 23 of the electric supply cable 19 is connected to a rheostat 25, the other 24 is led to the motor and returns to a screw 29 mounted on a metal plate 28 connected to a sliding contact 30 engaging the contacts 34 of the rheostat and provided with a switch arm 32 by movement of which the fan may be given any of three different speeds. A rubber strip 38 of angular cross section is held against the base by a plate 36, and serve as a support for the fan. The hub 5 and other external parts may be of insulating material such as a synthetic resin.

Inventor: MEYER ROBERT
IPC: D06P3/74
Filed: 1952-02-25
Abstract: Affinity for acid-dyestuffs is conferred upon polvacrylonitrile or copolymers of acrylonitrile with monomers free from oxo-groups, such as acrylamide or an acrylic ester, by mixing the polymer with an aliphatic mono-or di-amine containing not less than ten carbon atoms in the molecule, in the presence of an inorganic substance of acid character, the mixture being formed in the presence of a solvent, such as dimethylformamide, and being heated to effect dissolution of the polymer and amine.  Amines specified are diethyl-n-octylamine, diheptylamine, cetylamine, stearylamine, distearylamine, oleylamine, diethyl-laurylamine, bis-diethyl-tetradecylamine, and dibutylethylene diamine. Inorganic substances of acid character specified are hydrochloric, hydrobromic, sulphuric, phosphoric, perchloric, and boric acids and other substances which act as acids such as zinc chloride, boron trifluoride, and boron trifluoride etherates. The acid and base may be employed in the form of the salt formed between them, or an excess of the same or different acid or base may be employed.  The treatment is preferably carried out at a temperature of between 60 DEG  and 150 DEG C.  The solutions may be evaporated to yield solid products, such as films or filaments, which may be dyed with acid dyestuffs.  The Provisional Specification describes also the use of toluene sulphonic acid as the acid reagent, and of other nitrogenous bases such as ammonia, hydrazine, methylhydrazine, diethylamine, ethylene diamine, hexamethylene diamine, butylamine, aniline, phenyl hydrazine, cyclohexylamine, piperidine, and piperazine. Also described is the use of copolymers of acrylonitrile with vinyl acetate, vinyl chloride and vinyl ethers, polymers and copolymers of 1,1-dicyanoethylene and poly-p-cyanostyrene.
